![js中有["1","2","3","4"]这样一个string，怎么把它变成array](/aiimages/js%E4%B8%AD%E6%9C%89%5B%26quot%3B1%26quot%3B%2C%26quot%3B2%26quot%3B%2C%26quot%3B3%26quot%3B%2C%26quot%3B4%26quot%3B%5D%E8%BF%99%E6%A0%B7%E4%B8%80%E4%B8%AAstring%EF%BC%8C%E6%80%8E%E4%B9%88%E6%8A%8A%E5%AE%83%E5%8F%98%E6%88%90array.png)
因为英文在参数传递转换两边格式一样所以没问题．
而中文状态下的解析会出现构造组合问题．出现类似繁体的乱玛．
可以这样解决：
在js中把要传递的参数先经过 encodeURIComponent(var)这个函数转换．
再接收的PHP中用 $var=iconv("UTF-8","GB2312",$_GET['var'])把接受的变量转换成中文.
最后在PHP传递出参数的时候 用函数 $var=iconv("GB2312","UTF-8","Your message")转换一次．问题就解决了．
下面的例子是写在struts2框架下面的。验证邮箱是否已经存在，和数据库交互那部分没有贴上，省略了
